Power Supply; Removing The Power Supply Unit - Dell PowerEdge T20 Owner's Manual

CAUTION: Positioning the processor incorrectly can permanently damage the system board
or the processor. Be careful not to bend the pins in the socket.
a. Align the notches on the processor with the socket keys and set the processor lightly in the
socket.
CAUTION: Do not use force to seat the processor. When the processor is positioned
correctly, it engages easily into the socket.
b. Close the processor shield by sliding it under the retention screw until it locks into place.
c. Press the release lever down and then move it inward to secure it with the retention hook.
6. To install the heat sink:
CAUTION: Applying too much thermal grease can result in excess grease coming in contact
with and contaminating the processor socket.
a. Open the grease applicator included with your processor kit and apply all of the thermal grease in
the applicator to the center of the topside of the new processor.
b. Place the heat sink onto the processor.
c. Align the heat sink screws with the corresponding slots on the system board.
d. Tighten the four screws to secure the heat sink to the system board.
NOTE: Tighten the screws diagonally opposite to each other. Do not over-tighten the heat
sink retention screws when installing the heat sink. To prevent over-tightening, tighten the
heat sink retention screw until resistance is felt, and stop once the screw is seated. The
screw tension should be no more than 6 in-lb (6.9 kg-cm).
NOTE: Do not remove the processor shield retention screw.
7. Connect the processor fan cable to the system board.
8. Close the system.
9. Place the system upright on a flat, stable surface.

peripherals.

system configuration.
